drive_group ‑forceDrivesOnline

Forces replaced drives online and forces the drives that were incorrectly marked as CRITICAL, WARNING, or MISSING to return to a NORMAL operational state.

DESCRIPTION

The Oracle FS System can mark a drive as CRITICAL, WARNING, or MISSING for many reasons that do not necessarily involve a mechanical failure. Unless a drive fails to power up, the data on the drive can be intact and accessible, and, therefore, recoverable. If the Oracle FS System marks only one drive in the drive group with a label that indicates failure, replace the drive. If the Oracle FS System marks two or more drives in the drive group as CRITICAL, WARNING, or MISSING, immediately run the drive_group ‑forceDrivesOnline command. Any of the drives that were incorrectly marked are brought online. If one drive is marked with a label that indicates failure after running the drive_group ‑forceDrivesOnline command, replace the drive.

CAUTION

After forcing the drives in the drive group online, if two or more drives in the drive group are marked with a label that indicates failure, exclude the drive group from the Storage Domain. Excluding the drive group from the Storage Domain gives you the best opportunity to safeguard the data. After the data migration operation completes, contact Oracle Customer Support for further instructions.

Note: After one or more drives have been replaced, the drive_group ‑forceDrivesOnline command brings the drives online if the drive group was not automatically brought online when the drives were replaced. When a drive is marked as CRITICAL, WARNING, or MISSING, the Oracle FS System rebuilds the data onto unused portions of the remaining drives or rebuilds the data onto a spare drive that is marked NOT_USED. While the system is rebuilding the data, the drive group operates in a conservative mode, with reduced performance and increased latency. The rebuilding process might require several hours to complete. If data is rebuilt onto a NOT_USED drive, the drive is marked with various indicators to communicate the current status of the data migration and rebuilding process. The system marks the drive as NORMAL when the data rebuilding process has completed. The replaced drive is marked as NOT_USED. After waiting a reasonable amount of time, if the drive group is not in a NORMAL or REBUILDING_ONLINE state, run the drive_group ‑forceDrivesOnline command.

Only administrators with primary administrator, admin1, or support roles are authorized to run this command.

OPTIONS

‑driveGroup: Specifies the fully qualified name (FQN) or the unique identifier (ID) of the drive group. When a Drive Enclosure is added to the Oracle FS System, the system automatically allocates the storage by generating one or more drive groups. The drive_group ‑list command displays the names of all drive groups that are defined on the Oracle FS System. The FQN consists of the name that the system generates preceded by a forward slash (/) character.

EXAMPLE

Task

Bring online any of the drives in the specified drive group that are currently offline.

Parameters

The fully qualified name (FQN) of the drive group: /⁠⁠ENCLOSURE01–DG001
